    Default Ubuntu 13.04 doesn't recognize USB hard drives

    Hi all,

    I've Kubuntu 13.04 and have a problem that I can' solve.

    I've been looking for information and it's quite clear that it's a problem that appears with all distros based on Ubuntu 13.04, but I've not find any solution.

    Problem is very simple: When I connect a hard drive via USB it's not recognized/automounted. I've try only NTFS partitioned disks, and as I've read, here is the problem (This problem is in 13.04, with 12.10 works ok)

    Anyone knows how to fix it?

    Many thanks in advance

    lsusb returns this:

    The USB 2.0 DockStation (Sharkoon QuickPort XT) is the JMicron.

    I've try a 2 terabytes disk MBR in this dockstarion and works ok (correctly recognized and mounted), the problem comes with 3 tb disks using GPT system and the JMicron USB 2.0 dockstation. The command sudo fdisk -l /dev/sdb returns this:

    AVISO: GPT (Tabla de partición GUID) detectado en '/dev/sdb'! La utilidad fdisk no soporta GPT. Use GNU Parted.

    Size is wrongly recognized as 801,6 gb instead of the 3000gb.

    I have to say that using a USB 3.0 dockstation there is no problem, 3tb gpt is mounted ok no matter if I connect to USB 2.0 or USB 3.0 connector:

    AVISO: GPT (Tabla de partición GUID) detectado en '/dev/sdb'! La utilidad fdisk no soporta GPT. Use GNU Parted.

    /dev/sdb1 1 4294967295 2147483647+ ee GPT
    As you can see, here it's correctly recognized as 3000gb, so the problem comes with USB 2.0 dock station and 3tb gpt disk, in both usb 3.0 and 2.0 connectors.

    The problem is not caused by the dock station since in Widows 7 works ok, it looks like some kind of incompatibility of Linux and jmicron dock station.

    What can I do?

    Many thanks
